Before bed: guacamole or a homemade squeezepouch (I love this brand) containing full - fat coconut milk, beets, chia seeds, cooked and cooled leafy greens, a tiny bit of collagen peptides, and banana).
My children love chia seeds and especially love these Mamma Chiasqueezepouches, but they are expensive (almost $ 2 each) and not ideal when I need 1 - 2 per child per snack.
